EMP effects on Solar Panels and wind generators?

Admin — Tue, 06 Sep 2011 18:20:19 +0000

My house runs completely on solar panels and I’ve heard that an EMP weapon "Electro Magnetic pulse" would fry them making them useless. I’ve also heard talk of possibly protecting electronics underground, is this possible? and if so how deep would you have to go? Naturally what’s on your roof would be toasted so what’s underground might be a large supply of solar cells packed away for panel construction later after the threat was gone. Of course if you’re hit again with another EMP you’re screwed right?

Also curious about the effects of an EMP on a wind generator that uses a permanent magnet alternator. I guess if the EMP magnetism was strong enough it could over heat and burn up the wire coils, not really sure of the effect on the permanent magnets.

I’ve read where it can actually magnetize an engine to the point it won’t even move. What steps can we take for our homes to prepare in case of an attack of this sort ?

Urgent question about electric generators?

Admin — Fri, 02 Sep 2011 20:42:50 +0000

So does an electric generator produce current when a magnet is making contact with the coil, or is it just the magnetic field? Do generator run out, or go bad (say because the magnet loses its magnetism, or the coil wears down)?

Does it matter what the coil is made of (nickel, copper, aluminum, etc.)

Please give right answers. My life depends on it!!?

1: If you doubled the number of coils and doubled the voltage, what would be the increase in magnetic strength?
It would remain the same, since 2 / 2 = 1
It would be 4 times as strong, since 2 x 2 = 4
You can’t increase magnetism by increasing the voltage

2: What causes the loudspeaker cone to vibrate?
Sounds that come from the radio or TV
The movement of a magnet within a coil of wire with varying current running through it
The movement of electrons in the electromagnet

3: Why is wire wound in so many loops in commercial generators?
Many loops are needed to make AC electricity
Voltage depends on how many loops are used
No one is sure why they do it that way

4: Why are kilowatts used?
Because James Kilowatt invented electricity
So we don’t confuse them with watts
Using watts would result in much larger numbers

5: How many kilowatt-hours does a 100 watt light bulb use in 10 hours?
1 kilowatt-hour
1000 kilowatt-hours
.00

please help?

Using magnetic force to generate electricity?

Admin — Tue, 07 Jun 2011 11:07:04 +0000

So, I understand how electricity is generated via a generator by using magnetism to jump-start a movement in [loose] electrons (like in that of copper); however, how far do the electrons go and is there a finite amount? If they’re moving along the atoms in the copper, what happens at the destination?
Ah, I see.. I understood the loop concept in smaller things that were battery operated, but for whatever reason pictured it differently for generators… Okay… So, the electricity used to power things is really just kinetic energy from electrons jumping from atom to atom? (Sort of like how photons [and other higher energy forms like gamma rays] are generated when electrons jump from energy levels, but instead this is from atom to atom??)

Thanks, again..

Will a metal bracket interfere with a motor?

Admin — Sun, 27 Feb 2011 13:30:52 +0000

Hi, I wasn’t sure to place this question in engineering or physics, but it seemed more an electricity & magnetism question.

I am attempting to build a bicycle pedal-powered generator. A bicycle stand’s roller will move the DC motor’s (aka generator’s) shaft. I understand I will need a blocking diode (with a large heat sink) and also a voltage regulator and a pair of 12v batteries (it’s a 24v motor)…and lots of fuses in between (I am not taking any chances, but I am enjoying the attempt to build this).

However, I need to support the heavy motor / generator with a bracket. I purchased two 4-inch exhaust U-clamps to hold the motor to the platform, but the brackets have a strong magnetic attraction to the motor. Will this attraction (and the added metal of the bracket) interfere with the motor’s electrical generation capabilities?

The motor is a 24volt, 22amp capable of generating a maximum 350 watts, electric scooter motor XyD-6D permanent-magnet motor, 2600rpm. Thanks!

Free energy tutorial and magnetic generator plans

www.MagPower.ustutorial and testimony of building a magnetic free energy device that generates free electric energy for home use, to find out how this has been done visit www.MagPower.us Follow this easy set of plans to build your own Magniwork Magnetic Electricity Generator for your home or business. A complete system can be built AND installed easily, and for less than 0! The Magniwork plans are getting rave reviews. Great business opportunity for those who wish to build and install these systems! http Did you know that you could completely eliminate your power bill, by constructing a zero point magnetic power generator? A Zero point magnetic power generator is basically a Free Energy Generator. It uses magnets, and magnetic force to induce perpetual motion. It runs by itself, indefinitely without stopping, thus creating completely free electrical energy, which can fully power your home for free. A Perpetual motion device refers to a machine that runs perpetually ie indefinitely, and produces a larger amount of energy than it consumes. Thus, it produces free energy indefinitely, runs by itself, without having to need a third-party device or resource to power it. The free energy devices have been suppressed by the corporate world, because such devices, would allow people to create their own energy for free, which would ultimately shut down the big energy corporations, because people won’t need to pay anymore for electricity to fill their pockets. Can this device be …
